'GRAPPLE.

SPECIFICATION forming part of Letters Patent No; 283,422, dated August21, 1883,

Application filed July 6,1883. (No model.)

To all whom it may concern.-

Be it known that I, ALBERT SANFORD, of Oshkosh, in the county ofWinnebago and State of Wisconsin, have invented certain new and usefulImprovements in Grapples; and I do hereby declare the following to be afull, clearyand exact description of the same,

referencebeing had to the accompanying drawings, forming part of thisspecification, and to the figures and letters of reference markedthereon.

to which the hooks are pivoted; Fig. 3, a-detached view of the partwhich connects the aforesaid casting to the band or ring of the grapple.Fig. 4 is a view of a modified form of the grapple.

Similar letters of reference in the several figures indicate the sameparts.

The hooks are represented by the letters A A, the casting to which thehooks are pivotedby B, the bar which connects the casting to the band orring by C, and the band or ring by D.

v The casting B is provided with two slots or recesses, 12 b, arrangedat an angle to each other, within which are pivoted the upper ends ofthe hooks by means of pins a a. The lower walls of the said slotsconstitute stops or shoulders, as seen at a a, to limit the approach ofthe points of the hook toward'each other, so as to prevent them fromstriking and injuring each other, while the upper walls of said slotsalso form stops at a a to prevent the hooks from opening beyond thepoint needed to accommodate as large a piece of timber as the length ofthe hooks will clasp.

5o Said casting is further provided with an upper projecting eye, b,which is adapted to work freely between the ears or lugs c c of theconnecting-bar 0, being held therein by means of a pivot-bolt, c, asshown in Fig. 1. The upper end of the bar 0 is united to the band orring D by a swivel-connection, as shown.

If the grapple is to be used on a bar carried by hand, the bandD ispreferably divided and provided with a clamping-screw, e, as shown inFig. 1, so as to enable it to receive such bar, and be tightly clampedin position there on; but when the grapple is intended for use upon anordinary fall' the split band may be displaced by a solid ring for theaccommoda tion of the hook of the block. The jointing of the casting tothe bar 0 and the connection of the latter to the band or ring by aswivelconnection gives a universality of movement to the grapple, andrenders it possible to grasp with the hooks a piece of timber, inwhatever position it may be.

Another mode of effecting the universaljoint connection between thehook-supporting casting and the lifting band or ring is illustrated inFig. 4, and consists in forminga ball or spherical projection upon thecasting, and a socket for such ball to work in upon the carrying band orring, the same result being accomplished by this arrangement as by thatshown in Fig. 1.

hooks is such that they open automatically when they strike a piece oftimber, and close and hook into the timber as soon as raised, and allthis without the necessity of any ad justment by hand.

The construction of the casting with the stops on each side of thehooks, while enabling the hooks to hang with their points directlyopposite, prevents said points from passing each other and becomingterfere with their automatic spreading and closing when acting upon thetimber. The upper stops, 0* 0, also prevent the hooks from striking thebar and the hands that are bold ing the bar.

The whole device is of simple construction, and after practical testshas been found to save a great deal of time and labor in the handling oftimber.

The constructlon and arrangement of the jammed, so as to in- I claim asmy invention- 1. The combination, with the hooks, of the I 3. Thecombination of the hooks, the cast- 15 ing to which the hooks arepivoted, provided with. the projecting eye at the top, the connectingbar having the lugs, between which said eye is pivoted, and the bandor ring to which said connecting-bar is swiveled, the whole 20constructed and arranged substantially as described, and for the purposespecified.
